2n3055 audio amplifier with transistor, Powerful audio amplifier with 2n3055

  • C1 capacitor governs the low frequencies (bass), with the capacitance grows, the lower shorter intervals are increasingly high.
  •  Capacitor C2 regulates the higher frequencies (treble), with the capacitance grows, the higher frequencies are getting quiter.
  • This is a class B amplifier, this means that the current must flow through the transistor end, even if there is no sign at the entrance. This current can be adjusted with the 500 Ω resistor trimmer.
  • As this increase present, the sound of the amplifier is better, but the effect transistors are more heating. But if this deceases current, the transistors are not very warming, but the sound gets worse

  1. Assalam o Alaikum!
    I am going to make this circut.
    Please send me the PCB layout.
    May I use BU508, D1047 instead of 2N3055
    Thanks

  2. I am going to make this circuit.
    But i have a confusion ,
    What its output power with 30v
    And 50v
    Is it able to give 150w rms

  3. THIS IS AN CLASSIC 40W PHILIPS AUDIO AMPLIFIER, 1972 OR SO.
    I WOULD LOVE TO DO IT, DO YOU HAVE AN PCB LAYOUT FOR THIS?
    THANKS A LOT
